" RING CLAMP.

"Application filed January a0, 1926. se ria'l 1\'l'o., 82,541.

This invention relatesto improvement in clamps for use uponpistons in compressing nately arranged cutout portions provided in.

. the piston ring within the -grooves defined therein to permit the insertion of the pistons and rings within cylinders.

Another object of my invention resldes in the specific construction of the clamp being relatively wide and split having one end of a relatively narrow strip 'plvotally secured adjacent one end. thereof" and -ex-.

tending across its opposite andv adjacent end and including an elongated slot-with alterits adjacent side edges for selective engagement with the headedstud provided on the clamp for compressing and locking the rings precedent to their insertion, with the piston, within a cylinder bore. e I

With the above and other objects in view, the invention further includes thefollowing novel features and details of construction, to be hereinafter more fully described illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawing Figure 1 is an elevation of a piston with my invention applied thereto.

Figure 2' is a top plan view thereof.

Figure 3 is an elevation of the piston with the invention applied thereto when inserted within a cylinder.

Referring to the corresponding parts the reference character 10 indicates a pistonand 11;a plurality of piston rings fitted .within the, usual .grooves defined therein, all of the above being'of the usual and well known construction and forming nopart of the-present applicationfor Letters Patentbut being merely shown for. purposes of illustrat ng 1n bringing forward the" novel advantages of the above entitled invention.

pivotally'mounted adjacent one end of the band and having its opposite end extending across the opposite end thereof, and means the pistons and rings withinthe cylinders I 1. A clamp forv use upon rings and pistons provided upon the opposite end of the relatively wide band for locking the relatively narrow band in a desired position upon the first mentioned band to compress the rings upon the piston.

2 A clamp for use upon rings and pistons therefor comprising a relatively Wide circumferentially split band a relatively narrow arcuate-shaped band having one end pivotally mounted adjacent one end of the first mentioned band and having its opposite end extending the major portion of its length across the opposed end of the relatively Wide band, the relatively narrow band including an elongated slot therein With-outout portions disposed in staggered relation Within its opposite side edges, and a. headed stud mounted upon the outer side of the corresponding end of the relatively Wide band and adapted for selective engagement within any one of a plurality of the cutout portions in the relatively narrow band for compressing the rings to permit the piston and rings therefor to be readily and easily fitted Within the bore of the cylinder block.

In testimony whereof I affiX my signature.
